Liability shifted onto the user
You are agreeing to accept the service "as is" with no guarantee of safety or function.
“Our Products, however, are provided "as is," and to the extent permissible by law, we make no guarantees that they always will be safe, secure, or error-free... DISCLAIM ALL WARRANTIES...”
What that means: You have limited legal recourse if the service fails or causes harm due to its unreliability.
Meta provides its services without any warranty of safety, security, or function, effectively shifting the risk of errors or failures onto the user.
